Unison Legacy DR with D20

Dimming with Unison Legacy DR racks is not ideal. Below 6% the unit will misfire (jump from full to off and back), but above should dim smoothly. Unfortunately there is no way in the older software to set a minimum threshold and avoid the poor dimming below 6%.

We do not recommend using Source 4wrd with Unison Legacy DR dimming.

We do not recommend using Source 4wrd with a Dimmer Doubler.

Smartbars and Smartpacks:

Smartbars and packs do not have many settings that can be changed. The good news is that they run unregulated at all times. This means that S4wrd can function on these dimmers. They may appear steppy at some points of the fade, but they will dim.

REPORTING DIMMER SETTINGS FOR NON-ETC DIMMERS

If you are using S4wrd with another manufacturers dimmers, and have found settings that work for you, please let us know so we can share that information with other users. To report the proper settings, please e-mail the rack and dimmer information and settings to service@etcconnect.com.
